Okay this is excellent content, thank you!

I went through and fiddled with some more stuff to try and get this working to no avail. However, it inspired me to take apart netboot.xyz a bit more, and I was able to grab an efi and get next boot to load the efi file. It took me too long to realize you need the console tty arguments as part of the boot cmdline to get it working interactively, but after I got there I got it netbooted. Sadly though, it almost immediately runs into an OOM condition and thus isn’t practical on a free tier x86 asset. It would probably work on an aarch64 node, but I already have my allotted arm node spun up and working so I don’t have a free one to practice with.

Solid write-up though, thank you for putting that together!
